A survey of the LEAR experimental programme

Abstract

During the first period of operation of the low energy antiproton ring (LEAR) from 1983 to 1986, antiproton beams were supplied for several experiments at an intensity between 105 and [Formula: see text]. A first exploration was made of several subjects in physics, including [Formula: see text] and [Formula: see text]–nucleus interactions, [Formula: see text]–atoms, and various annihilation channels. After an improvement by a factor of 5 for the [Formula: see text] production at CERN in 1987, a new generation of experiments is expected to complete the previous studies and to cover new subjects concerning fundamental symmetries.
